org.apache.cxf:cxf-rt-rs-security-sso-oidc is an Apache CXF Runtime OpenId Connect library.

Affected versions of this package are vulnerable to Improper Access Control. There is a vulnerability in the access token services, where it does not validate that the authenticated principal is equal to that of the supplied clientId parameter in the request. If a malicious client was able to somehow steal an authorization code issued to another client, then they could exploit this vulnerability to obtain an access token for the other client.
